Abstract

MÉTODOS PARA MEDIÇÕES DE AUTOINTERFERÊNCIA E INTERFERÊNCIA DE ENLACE CRUZADO EM BANDAS DE ONDA MILIMÉTRICA. Trata-se de métodos, sistemas e dispositivos para comunicações sem fio para medições de autointerferência ou interferência de enlace cruzado em um equipamento de usuário (UE). Um UE pode receber informações de configuração de uma estação-base que indica um ou mais valores de índice de formato de slot (SFI) que são compatíveis com medições de autointerferência e interferência de enlace cruzado. Com base no SFI (ou SFIs) configurado, o UE pode medir a interferência em múltiplos símbolos, que podem ser usados para estimar uma quantidade de interferência de enlace cruzado ou autointerferência, e o UE pode transmitir um relatório de medição para a estação-base. A estação-base, com base no relatório de medição, pode identificar um ou mais SFIs compatíveis, pares de feixes ou combinações dos mesmos para comunicações subsequentes com um ou mais UEs. As medições de interferência podem identificar a interferência de enlace cruzado no UE que resulta de transmissões de um UE diferente, ou podem identificar a autointerferência de comunicações simultâneas de múltiplos canais em um mesmo UE.METHODS FOR MEASUREMENTS OF SELF-INTERFERENCE AND CROSS LINK INTERFERENCE IN MILLIMETRIC WAVE BANDS. These are methods, systems and devices for wireless communications for measuring self-interference or cross-link interference in a user equipment (UE). A UE may receive configuration information from a base station that indicates one or more Slot Format Index (SFI) values that are compatible with self-interference and cross-link interference measurements. Based on the configured SFI (or SFIs), the UE can measure the interference in multiple symbols, which can be used to estimate an amount of crosslink interference or self-interference, and the UE can transmit a measurement report to the base station . The base station, based on the measurement report, can identify one or more compatible SFIs, beam pairs or combinations thereof for subsequent communications with one or more UEs. Interference measurements can identify cross-link interference at the UE that results from transmissions from a different UE, or can identify self-interference from simultaneous communications from multiple channels within the same UE.
